7 Application filedDecember 2, 1925. Serial No. 72,779.

- Our invention relates generally to well "well tubing while additional sections were tubing, more particularly to an improved so-called cage; for use in aproducing 011 well in con unot1on witha well packer, and

it consists in the combinations, construce I hens and arrangements herein descr1bed and claimed. I I An object of our invention is to prov de a cage which is adapted'to preventflow from the well'casing' into the well tubing below a packer when ;the packer and the .Ican be operated when in position 'in the scription; considered in conjunction with the I with the section 4 by the cage 6.-

.well casing to permit or prevent flow from the well .casinginto the well tubing, as desired. i

A further object of the invention is the ate and not. likely-to get outof order easily.

- otherobjects and advantages of the inven'- tion will'be. apparent from the following deaccompanying drawings, in which.

Prior to ourinvention, all such cages of which we-are aware were open when lowered in the well casing'and therefore con 1 siderable leakage. from the well casing' below Twell casin into the cage and thence upwarda packer in the well casing end portion ofthe tubular body-is enlargedv internally at 11' and provided with screw threads 'for engaging with the externally Y :sorew threaded lowerend portion of the sec- I enlarged irag-, V tion i of the well tubing; A) collar 12. is

Our invention obviates" theobjectionable 1 feature justmentioned of: priorcagesby providing a cage which is closed to flow from the well casing thereinto when the. cage is lowered to position in the Well casing and which" can be opened conveniently and easily when desired afterithas been lowered to-position in the well casingito permit .fiow' from; the

connected Theicage 6 comprises a' tubular'body, 8 en larged externallyadjacent to its upperend as at 8?, thus definingan annular shoulder 9 at the lower end' ofthe enlargement. The shoulder 9 [preferably is undercut and beveled as indicated at'lO. The enlarged upper secured by welding or in any other suitable known manner'on the tubular body, 8 in spaced relation to .the shoulder 9 and 'in 7 position to cooperate with the beveled por- 95 -tion'of the shoulder 9 to retain a rotary sleeve valve 13'again'st axial movement on the tubular body, the rotary sleeve valve and the portion-of the tubular body, encircled by n'umber of circ'umferentially spaced elongat- 5 ed ports 15 and l6,'respectively, whereby'the sleeve valve'13 can beturnedfon thetubular valvel3 carriesspaced spring fingers having inturned, rounded lower. end portions f adapted. to engage wlth depresslons 21 in the H accidental turning iniovement of the sleeve valve on thejbody .8 from. elther open or.

closed posit-ions without preventing operaof the shoulder 9. The collar 12 has an annular prolongation or reduced portion 12 7 at its upper end provided with beveled outer wall andithe lower end of the sleeve valve 13 is beveled to complement the beveled 'wall 'of the reduced end portion 12 of the collar 12. "lfhe collar 12 may depend below the lower end of the tubular body 8 and may have the lower end portion thereof ini ternally screw threaded for engaging with the externally screw threaded upper end portion of the section Yet the well tubing.

The upper end portion of the sleeve valve carries a circumferential series of spaced radial projections consisting of rollers 17 mounted on radial pins 18having the inner endportions thereof in threaded engagement with sockets in the sleeve valve. The purposev of the radial projections on the -sleeve valve will be presently described.

' Spaced slide rings 19 and 20, respectively;

on the-section 41 of the well tubing are connected by four equi-distan-tly spaced sp-ring "friction lat ch members 21 which are bow-ed outwardly intermediate theirends a distance sufficient to bear with considerable pressure against the inner wall of the casino; 1, the outer wall of each of the spring latch members preferably being roughened as indicate-d at 22 where it contacts with the inner face of the casing 1. The upper end of each of the spring members 21 fits in a socket 23 in the lower end :of the slide ring 20 while 'tlie'lowerend portion of each spring member 21-i-s loosely'received in socket 2l in the upper end of the slide ring 19, being justed within screw 28. i

netainedin'lthe socket 2 1 by a pivot pin 25 'which extends through alined transverse openings 26 and 2? inth-e member 21 and the ring 19, respectively. An adjusting" screw 28 is threaded througha radial open 111g ln the ring 1 9 nto the lower end of each. socket 2 1 and bears against the lower end of the spring member within the socket be flow the associ-ated pivot pin '25, whereby the pressure which the member 21 will exert on the inner wallof the casing 1 canfbe' adhmits by manipulation of the The ring19pis enlarged downwardly to providediametrically opposite lugs 29 hav mg sockets as atSO, in their lower ends in which substantially radial pivot elements are arranged to support the 'u'pperend portions of longitudinally curved elongated cam members 31 which "extend downwardlv along opposite sides of the section 1.

Thering 19 is held against rotation "on the section 1 of the well tubing by longitudinal guide ribs 32 which are provided on the section-1 and engage with longitudinal grooves 33in the inner wall of the ring 19.. The cam members 81 therefore will be held against swinging about the axis of the section 4. i

From the foregoing description of the various parts of the device the operation thereof may be readily understood. The rotary sleeve valve 13 is turned to closed position before the cage is lowered to a de sirable position in the well casing.- After the cage is in position in the well casing, the tubing is raised a slight distance. The engagement of the spring friction latching members 21with the inner wall .of the easing will hold the rings 19 and 20 and the cam members "31 substantially stationary in the casing. The upward movement of the and the ring 19 when the welltubing is being moved upward and the union 5 serves as a stop for limiting the relative axial movements of the ring 20 and the well tubing when the, well tubing is movingdownward.

The rings 19 and 20 of course are connected by the spring members 21 to move substantially in unison. I i

It is to be observed at this point that the lateral distance from the plane of the upper end portion to the'plane of the lower end portion of each elongated cam member 31 is greater than the distance between adjacent radially projecting rollers 17'. Gonsequently the rotary sleeve valve can again-be closed when desired after it'has been opened in the manner described by lowering the tub ing in the well bore relatively to the ring 1.) and cam members 31, the lower end portionsof the cam memberscontacting with other of the rollers 1"? and the sleeve 13 being turned to closed position. Slight swinging movement of the cam members 31in one direction about the axes of the pivot elements 8O may take'pl-ace against the action of spring arms 30 to permit disengagement. of the last named radially projecting rollers 11 after the sleeve 13 has been closed. V ()bviously, our invention' is susceptible of embodiment in formso'ther than that which. is illustrated inthe, accompanying drawings and we therefore. CQDSiQQI as our own all such modifications and adaptations-there of as fairly fall within the scope of the apl pendediclaims. I V i lVe claim r 7' 1..
